Whether he was a closeted gay man or a kinda-fey straight man or a disaster bisexual or a desperate chaser or whatever it doesn't really matter because he was a horrible person for reasons that had nothing to do with that
Henrythe whole "Linsey Graham is gay" thing comes down to 3 things 1. he was Southern which can come off as fey 2. he was never married 3. making fun of gay people is fun and people are always desperately looking for "socially acceptable" ways to do it and still be liberal/left-wing.
